eyelash growth

i am only 17, and have a small penis, the doctor said he could give me some DHT to increase my penis size while i am still in puberty, but i already have normal levels. i would only use it for 2-4 months, but ive heard high DHT levels is the main cause for prostate cancer and prostate enlargment? is this true, would it be safe for a regular 17 year old to take DHT for 3 months just to boost maturity?

what affects could it have, any serious, eg potentially life threatening in the future. if i take DHT now does that raise my DHT levels forever, or just while im taking it? do levels reduce back to normal afterwards?

( please note i am not talking about DHT blocker which blocks DHT to prevent hairloss, im talking about actualy DHT that is produced testosterone but is much stronger)) ???

Your doctor must be sniffing glue or something. they don't manufacture DHT or sell it, it's only made in the body from your testosterone. I've taken testosterone injections for over 10 years and I've never heard of anyone buying or selling DHT.
